Understanding the warning symbols on an International truck's dashboard is crucial for maintaining vehicle safety and performance. This guide provides a comprehensive overview of the most common warning symbols, their meanings, and the actions drivers should take when they illuminate.

International Truck Warning Symbols

The dashboard of an International truck features various warning symbols that alert drivers to potential issues. Recognizing these symbols is essential for ensuring safe operation and preventing damage to the vehicle. Here are some of the most important warning symbols you should know:

  • ABS Warning Light: Indicates a malfunction in the anti-lock braking system. Immediate attention is required.

  • Brake Warning Light: Signals a problem with the braking system, such as low brake fluid or worn brake pads.

  • Check Engine Light: Illuminates when there is an issue with the engine. This could range from minor problems like a loose gas cap to more serious engine failures.

  • Coolant Warning Light: Activates when the coolant level is low. Add coolant promptly to avoid engine overheating.

  • Oil Pressure Warning Light: Indicates low oil pressure, which can lead to severe engine damage if not addressed immediately.

Understanding these symbols helps drivers respond appropriately and maintain their trucks effectively.

Importance of Color Codes in Warning Symbols

The color of warning symbols plays a significant role in conveying urgency:

  • Red Symbols: Indicate critical issues that require immediate attention. Continuing to drive may pose serious risks.

By paying attention to these colors, drivers can prioritize their responses based on the severity of the warnings.
